Describe the bug
If using _OR in a combiner it can't have the same value twice in the $whereClause. I came across this when trying to make a function to group WHERE clauses. Working on a fix now so hope to push that soon.

To Reproduce
Create a selecting statement using a where() and 2x eq(), with the first eq() having an _OR combiner

$db->selecting(
  "login_log",
  "login_id",
  where(
    eq("login_user_id", "1", _OR),
    eq("login_user_id", "2"),
  )
);

Expected behavior
The compiled SQL would be as follows

SELECT login_id FROM login_log WHERE login_user_id = '1' OR login_user_id = '2'

Environment (please complete the following information):

• EZSQL Version : 4.0.9
• PHP Version: 7.4.3
• SQL Driver: PDO:mysql
